Answer:
1.024x10^17
Step-by-step explanation:
5^5(16^2x5^3)^3
find the 5^5
3125(16^2x5^3)^3
distribute the power of 3 into the parentheses 
3125(16^6x5^9)
multiply 
3125(16777216x1953125)
1.024x10^17
 
        
             
        
        
        
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
 3x² = 147
 x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
 √a = a¹/² so (x²)¹/², and (x²)¹/² = 
x²×¹/² = x, therefore the solution is
x = +/- 7.
